Risto Eliel William Orko (né Nylund; 15 September 1899, Rauma – 29 September 2001, Helsinki) was a Finnish film producer and director.

With a career of over 60 years at the film studio Suomi-Filmi, Orko rose to be head of production and chief director in the 1930s. He became its CEO in 1945. In the 1940s, 1950s and 1960s, Suomi-Filmi produced hundreds of films and numerous shorts.

In the years 1933-43, Orko directed many films, including two (Aktivistit and Jääkärin Morsian), which were banned for being "overly patriotic". He had a joint cooperation with the German film industry during World War II. Orko also directed a Finnish-Soviet co-production, released into the American market with subtitles, entitled The Day the Earth Froze in 1959.
